Animation fiiea April 14,

To all whomit may concernf Be it known that LFni-:o M. Cmonr., a citizen of the United States, residing at Endic'ott, inthe county ofBroome and Stateof New York, have invented certain new and useful vIm'provements in. Tabulating-Card Printers, of which the following is a full, clear, and exact description. i

This invention lrelates to printing machines. More specifically it relates to cardprinting machines and, from a still more specific aspect it'relates V.to machines for printingtabulating cards; i. e., cardsto be pnnched and employedin connection with tabulating machines' of the general type illustrated' in the United States' Patent No. 1,087,061, February 10, 1914, HfHollerith,

Before describing the' detailed construction of the preferred form of iillustrating al pluralitydetail endsectitinal View'taken partly in sec-v detail side elevation, partly i machine illus-l trated, I shall explain genera-llythe course device 16 severs each printed AVblank material' of the material through the machine. The

1) over suitable Guide devices to and around feed rollers or drumsll, 12 (see Fig. 4). The material then passes through a straightening device, enerally designated as 13, and thence around the platen 14. A type roll 15, inked as hereinafter described cooperates with the platen 14 to print the desired subject-matter on the material. A shearmg card from its neighbor as the printed material is about to leave the platen. Devices including rollers 18 and 19 receive and remove the cards from the 4platen and transfer them to the receptacle or tray 19.- In certain cases.

it is desirableto remove the corner of a card. This may be efiected by means hereinafter disclosed. I shall now proceed to describe the construction. of the various instrumentalities.

The machine comprises a base 20 and pedestal 21 which support the entire mechanism. The pedestal .carries journal braekets 22 Which in turn support a shaft 23 upon Which a roll 10 of blank material is detachably and rotatably mounted. The blank' material passes from the roll 10 (see Figs. 1 and 3) over a flanged idler or guide roller 24, journaled on the frame of the machine, thence over a guide plate or trackway 25 provided With side flanges 26, 26, to track the material. By virtue of the structure thus far described, the roll 10 or rolls 10 may be located at one side of the machine. The material passes from the track-way 25 around a flanged idler orguide roll 27 (Fig. 4) suitably journaled in the frame of the machine and thence to the feed rolls 11, 12. The feed roller 11 (Figs. 4 and 5) is journaled on a stud 28, suitably mounted in the frame of the machine, and a spur gear 29 vis secured to this feed roller-ll. The similar feed roller 12 is secured to a shaft 30 to Which a spur gear 31 is also secured, said shaft 30 being suitablvjournaled in theframe of the machine. The spur gears' 29 and 31 mesh with each other so that by rotating the shaft 30 both feed rollers 11 and12 Will be driven to propel the material. The shaft 30 has secured thereto a second spur'gear 32 driven Vby a train ,of gears hereinafter described.

Calling attention to Figs. 4, 5, 7 and 17, it Will be seen that the platen or main drum 14 is secured to a shaft 33 in the frame of the machine. A Worm gear 34 also secured to the shaft 33 meshes with and is driven by a worm 35 on a worm shaft 30 which is coupled to the shaft of an electric or other motor 37 through a coupling' device 38. The coupling device is shown to be of the pin and radial slot type and effects a readily detachable drive connection between the worm and motor and one Which is operative although the worm and motor passes from the roll 10 (Fig.-

suitably journaled pivot 40 5 and 7) secured to a shaft 42 suitably journaled in the frame of the machine. The shaft 42 has also secured thereto a spur gear 43 Which meshes with the spur gear 32 above referred to as being` secured to the shaft 30 of the feed roller '12.

The above described parts including the gear-ing interconnecting the platen or mam drum 14 and the feed preferably so designed that the linear or peripheral speeds of the rollers 11 and 12 will be equal to each other but slightly greatelr than that of the drum 14. By virtue of t lis are obtained as Will hereinafter appear.

I prefer to provide means for removing` the curvature or at least a part of the curvature of the material so that the discharged printed cards will be substantially flat or plane. It will be apprcciated that the pre-set or curvature of the material will mcrease as the size of the roll 10 diminishes so that the curvature-removing means should be adjusted to meet this varying condition. I therefore automatically control the adjustment of the curvature-removing-means in accordance With the varying diameter of the roll 10. One form of structure for accomplishing these results is shown in Figs. l, 2, 4, 16 and 18 and may be constructed substantially as follows:

A bar 45 is secured to a shaft 46, suitably journaled for oscillation in the frame of the machine. A second bar 47 is secured to the shaft 46 in such position that the material will pass between said bars 45 and 47 as clearly shown in Fig. 10. The bar 47 carries a-bracket portion 48 to which a stub shaft or pivot pin 40 is secured. A third bar 50 is oscillatably mountcd on the pivot 49 and is provided with a pin 51 which passes through tho inclined or cam slot, 52 (Fig. 4) provided in the fran'ie of the machine. The shaft 46 has secured therelo an arm 53, shown in dotted lines in Fig. 2. to Which a link 54 is pivotally connected. The latter is adjnstably and pivotally connected at its other end to the short arm 55 ofa bell crank lever pivoted at 50 on'the frame of the machine. 'The long arm j57 of the bell crank lever carries a roller 58 Which engages the periphery of the roll 10.` irecting specific attention to Figs. 1,A 2, 4 and 16, it will be seen that as the roll 10- becomes smaller the shaft 46 and bars 45, 47 will move in a counter-cloclnvise direction about the axis of said shaf t` and the cam slot 52 and pin 51 will cause the bar 50 to move in a clocluvise direction about theand with respect to the bars 1.15, The paper or material will there foro bc rollers 11 and 12 are design important functions and results llO ii'tiaonr I k bent at a sharper angle as it passes'through the straightening device 46-47-50 'and the effectively removed theresecured to a corresponding one of shafts61, 61, 61 (Figs.

. 4 and 6) suitably journaledintheframe of and is driven by plat e 66 (Fig. 2)' and' a thumb i threaded at speet to the is eccentric with vmeans for holding sition. Obviously by .moving the members the machine; Each of the shafts. 61 vhas 'se- 'cured thereto a corresponding one of three spur' gears 62 each of which meshes with the gear 40. It will be noted that each of the rolls rotates tinv a direction opposite to that of the drum 14 and the design of parts is such that periphleral speed of each rql'l 60 is equal to that gf the drum 14. It is desirable that means e be adjusted toward and `away from the drum or platen 14. This means mayI assume the form of eccentrieally bored bushings, such as that shown at 65 in Fig. 13, provided, one'for either or both ends ofthe vshafts 61 of the i'olls 60. Each of these journal bushings is shown provided with 'an' integral or finger-.piece 67 whereby it may be oscillated. Set screws 68 extending through -the slots 69 in the plates 66 permit adjustment and provide the parts in adjusted po- 67 in the properone of'opposite directions the-shafts 61 and rollers 60 may be caused to approach or 'recede from the drum 14. I shall now describe the type roll 15 and the means for actuating the same, attention loe-- ing directed to lifigs.V 3, 4, 5, 6 and 20.

screw 82 extends. In view of the description set forth in connection with the genern f 'ally similar parts associated with the presser rolls 60,iit willV be obvious that, by virtuc 'of the elements 7 8 to 82, the btype roll 15 may be adjusted toward or away from the drum 14 and held in adjusted position. The

`bracket 79 is preferably detachably connected to the frame of the machine as by means of one'or more cap 'screws 85 and one or more dowel pins 86. By constructing the dowel pins and' the correspo'nding holes which receive them of hard metal, and accurately maehinin them a means is pro-- vided whereby the racket 7 9 and supported parts may. not only restored to exactly the same position as was occupied before such removal." The shaft 71 hassecured thereto a spur gear which a,

meshes with and is driven by 'the gear 40 so 'there will be no slip between the type, carried by the sleeve 15, and thejperiphery of the drum 14. The hub 91 of the gear 90 abuts against the frame portionv 75 and also the endwise movement ofy a sleeve 92 which surrounds the shaft 71 and abuts at its other end the type roll 15.

Before or at the time thematerial 'leaves the drum 14 it is cut or cards of the desired dimension (length in this case). The shearing mechanism is automatic and accurate in its operation and is preferably constructed as follows. (See particularly Figs. 4, 5, 6, 8, 16, 17 and 19.)

lThe -drum- 14 is So cnmferential or peripheral length is an' exact multiple of the desired card length. In the present case the circumferential length of the drum' 14 is three times the card length. The drum'i's provided With'threc equi-angu- `larly spaced -knives whose outer leading edges are straight and parallel with respect' the drum 14 an-d form cutting It will be understood that the drum edges.

The inovable knife '16 is adapted to proper time in the cycle of operation to per- 4 Means a re provided for automatically actuating the knife 16 to perform this function and `may be constructed Vas follows:

- The knife 16 is' pivotally degree of pivotal movement With respect thereto.

The end 111 of the arm 106 is slotted as indicated at 112 to slide ona pin 113 secured to the frame of the machine. It will be seen that rotation of the eccentric 110 will so move the lever 106 as to' cause the knife alternately to approach and recede from the drum 14, the path of movement of the knife' 16 being substantially an ellipse. In order to aid in supporting and operating the arm 106 in its above described/movement, a lateral extension 114 is provided on the lever 106 and this extension has detachably secured thereto (Fig. 17) a member 115 which forms an eccentric strap 116 for an eccentric 119 secured to the sleeve 122 in a manner similar to the Securing of the member 110.

The means for driving the eccentric 110 may be constructed as follows.

The hollow hub 120 of the eccentric is.

operatively connected, by means such as set screw 121, to a sleeve -122 surrounding but rotatable with res ect to the shaft 33. f Endwise movement of the sleeve 122 is limited by abutment with the members 110 and 117' into which the sleeve extends' The sleeve 122 has a lso secured thereto, by suitable means such as a set screw 123, a gear 124. This gear 124 (Figs. 5 and 8) meshes with an idler gear 125 Which in turn meshes with and is driven by the gear 43, hereinbefore described as being driven by the gears 40,- 41. It will be noted that each of the knives or blades 100 is provided with a radiallyoutward-projecting lug 126 (Fig. 19) Which is irovided with a beveled surface adapted to lbe engaged by the knife 16. It will be noted further that the cutting edge of the knife 16 is in the same plane with -but is not parallel` to the axis of the drum 14' (Fig. 19) so that the shearing eonunences at one edge of the card material and proceeds across to the opposite edge.

The above described parts are so designed that before any knife 100 reaches the position occupied by the lower left hand knife 126 is engaged by 'the knife 16 and cams the latter into proper shearing alignment with respect to the adjaeent knife 100. As the movement of parts proceeds the knife 16 moves substantially radially' inward to shear the card material until the inner-most position of the knife 16 is reached, at'which time the material is cut across its entire width. As the movement of parts proeeeds further the knife 16 is moved away from the drum and ultimately, and at the proper time, contacts with the lug 126 of the next knife 100, and so on.

Before any card has been severed from the remainder of the material its leading edge will have passed. between the rollers 17, 18, and gripped thereby. For reasons hereinafter stated these rollers 17 and 18 are preferably so driven and so timedthat they will present the same points on their peripheries to any card entering between them as they 'do to any other card so entering but their linear peripheral speeds are slightly in excess of that of the drum 14. It will be seen that these two requirements are not inconsistent and are readily obtainable, the first being a function of angular velocities and the second a function of angular velocities of rolls 17 and 18 and the radii of the latter. I shall now proceed to describe the driving means for the rollers 17 and 18, having specific recourse o F igs. 4 and 7 for this purpose.

The rollers 17 and 18 are each secured to a corresponding one of the shafts 130, 131 suitably journaled in the frame of the machine. Each of the shafts 130, 131 has secured thereto a corresponding one of identical gears 132 and 133 which mesh with each other. The gear 133 meshes also with a suitably journaled idler gear 134 which in turn meshes with and is driven by the gear 40. The rollers 17 and 18 are preferably provided With card-corner-clipping devices. Before proceeding to describe these devices, I shall describe the'means for conveying the cards to the receptacle or tray 19.

By inspecting Figs. 1, 2 and 9 it will be seen that the cards pass from the rollers 17, 18 over a plate 135, suitably secured to the frame of the mach1ne,.and thence into the box or tray 19, secured to and carried by the pedestal 21. The tray 19 is shown provided with aslidable member 136 which is substantially the same in construction and operation as a book rack. As cards accumulate in the tray the member 136 is automatically slid to the right (Figs. 1, 2, 9, 10 and 12) by means now to be described.

rl`he gear 132 of the roller 17 has secured thereto a roller 137 adapted to engage and operate the arm 138 of a bell-crank lever pivotally lnounted at 139 upon the frame of the machine. The arm 140 of the bell-crank is provided with a roller 141 adapted to engage the member 136 or the extreme lefthand one oflthe cards in the tray to propel the same to the right. Those parts are preferably `so designed that, in the interval of time between the entry of each card anda succeeding card into the tray, the roller 141. is operated to move the member 136, and any cards in the tray, to the right a suflicient distance to make room for the next card. The arm 140 is biascd away from the cards by means of a` coiled spring 139* (Fig. 10).

Attention is called to the fact that the shaft 131 of the roller 18 is journaled in an eccentrically bore'd member (Fig. 13)

Vaway from the roller 17 and held Which is. provided with a nlanually opel-able member 142, set screw 143,V etc., whereby the roller 18 lmay be adjus'ted toward o r in adj usted position'. ,In view of the foregoing description of the similar parts 66, 67, 68, 69, etc., no further description is necessary. It will be noted 'further (Fig. 13) that the cardengaging peripheries of the rollers 17 18 are-provided with annnlar ribs 145 which are so spaced as to engage the printed card material between theV printed columns. In this way smudging or. blurring of the printed 'matter is avoided.

As mentioned above the rollers 17 18 are preferably provided with devices for clipping the corners of the cards or card material. One form of` such device is illustratedin Figs. 13, 14 and 15 in detail. The rollcr 18 is there shown provided with an insert 146 of'steel 'or other suitable material edge 151 which and having a raised portion 147 providing a diagonal cutting edge 148. The'roller 17 is provided with an lnsert, 140' having a raisedportion 150'and diagonal cutting are complementary` toV the elements 147, 148. The design is such that one of the two trailing corners of each card, entering between the rollers 17, 18. is clipped or sheared Voff by the cooperating cutting cdges 148-151. In, order to insure that these clippings will not be thrown tosucli position as 'to injure the' machine 'or the cards, I preferablyprovlde means for holding each such chpping to one ofthe rollers 17. 18 until it is in proper position to be .discharged thcrefrom.

For example, static or While the `clippings When-releasedlfrom the said roller maybe allowed to'dropjy gravityin certain cases gravity alone may not. prove. effective. frictional electricity may at times cause the clippings toadhere to the rolls.

I- therefore propose not only to provide means for vholding eachl clipping to thefiroller until the discharge position is;

reachedbut alsomeans for positivcly forcing each clipping away from1 the roller when the 'discharge position is reached. A now the insert 149. through the /port 1.56 pro-` preferred form of such means is illustratedv in Figs; 9,

10, 11, 13, 14 and 15 and may be 'constructed substantially as follows.

The shaft of 'one of the rollers 17, 18. in the present case the shaft 130 of the roller 17, is provided withla duct 155 which communica'tes ..at one end `'with a port 157, in

vidcd in the roller 17. The other endof the duet or passage 155 terminates in a radial branch 159.V The latteris adapted to cooper-ate with the ports 160, 161. provided in a member 162 partiallv surrounding the.

shaft 130 and forming therewith a valve as clearly indicated in Fig. 11. The member 162 is provided with `ducts or passages 163, 164 leading from the .ports 160, 161 to upper der 165.

I pressure in the and lower ends respectivcly of a-cylinder 165 of a pump .which is suitably secured to the frame 'of the machine. It will be seen that when the parts are in the position shown in Fig. 9 and indeed vas long as the port 159 registers with the port 161 communication is established between the port 157 and the lower part .of the cylinder 165. At this time the insert 149 moves from the position shown in Fig. 9 to a position below the axis of: the roller. 17. lVhen the insert 149 and its port 157 are substantially directly below the axis of theroller 17 communication betwcen the lower part of the cylinder 165 and the said port 157 is cut off, and communication between the upper end of the cylinder and the port 157 is established through the 'following passages: 163-160-1594- 155- 156-157. Mechanism is provided for automatically causing the pump to create a suction or negative pressure at the port 157 when the ports 159-161 'are in'communication and for providing a positive pressure at. the port 157 when the passages 159-160 communicate. I shall now proceed to describe the particular form of such mechanism illustrated in thev drawings.

The shaft 131 has secured thereto a cam 170 adapted to engage and operate the arm 171 of a bell-crank lever pivoted at 172 on the frame of the machine. The lother arm 17 3 o f thev bell crank is a suitable pivotal connection with the piston rod 17'5 of the pump. The rod 175 is pro'- vided with a shoulder 'ortion (Fig. 10) adaptedtoy engage the lower side of and move the piston 176 upwardly in the cylinthe piston and connected parts toward the opposite positlon; The parts are preferably so timed that when the ports 159-161are in connected at 174, by

A compression ,spring 177 biases V communication the piston 176. is moving upwardly and creating a suction or negative lower part of the cylinder and'consequently at the port 157. This suction holds the clipping to the roller 17. 'Communication is established between the ports piston is permitted to 159-160 before the move downwardly. Bearing 1n mind that upward movement of the piston 176 compresscs air in the upper .part of the pump cylinder it will vbe appreciated that 'when' 'the ports 159-160 communicate. a blast of compressed vair is discharged through'4 the port' 157 'thus positively impelling the clipping'jdownwardly away*from the roller 17 and into a suitable' chute or receptacle 180. The abovedescribed cycle is repeated as 7each clipping of the-corner of a card is efl'ected.

Various forms of mechanism maybe provided for supplying' ink t o the t peroll 15. I prefer. however, to employ t e form of means illustrated generally -1n Fig.` 22 and more in detail in other views hereina'fter referred to. I. shall first describe .the 'nik-
